Zurn is proud to introduce its Green Roofing Drain product line, specifically suited for the unique needs of a green roof installation.

Having proper drainage on a green roof is a critical aspect of the system. If the system is not able to drain properly it can negatively impact the vegetation due to over-saturation of the soil. As the soil takes on excessive amounts of water it continues to add weight to the roofing structure. This added load has the potential to compromise the structural integrity of the roof. In order to prevent these situations from occurring, the roof drain must allow adequate flow through the drain at all times.

Zurn Green Roofing Solutions – Modular System

Z163

If code requires a primary drain and an overflow drain

side by side, the Z163 (shown above) is an ideal solution.

It can provide spacing to grid around the drains and easy

installation with the Zurn Top-Set™ deck plate. The Z163

can also be incorporated with drain risers (-DR option)

which allows for easy vertical adjustment.

Modular green roofs are installed differently than layered green roofs, requiring a different style of roof

drain. Zurn offers a variety of roof drain solutions suited for modular green roofs, such as the Z163 and the

-84 options, both shown below.

If stone ballast is being utilized around

the drain, the -84 option (shown above)

will allow for flow through the drain

while also keeping the stone ballast out.

More Sustainable Solutions from Zurn

Zurn Green Roof Drains

Siphonic Roof Drains

Zurn siphonic roof drains utilize a baffle to eliminate

all air from the piping system. This innovative design

solution provides multiple benefits to the building, such

as reducing both the amount of drainage pipe required

and the diameter of the drainage pipe.

More Green Roof Applications

The Z110-AI is supplied with an auxiliary inlet for

additional drainage capabilities into the roof drain.

In addition to our green roof drains, Zurn also offers a

wide selection of planter-style drains for rooftop

promenade decks. If your application is beyond what

we offer off of the shelf, we can custom-engineer a

unique green roofing solution for your project.

Cool/Reflective Roofs

Cool roofs, also known as reflective roofs, are

considered a “green” alternative to traditional-style

roofing. This type of roof offers environmental benefits

by reflecting sunlight and heat instead of absorbing it.

the Zurn roof drain with Top-Set™ technology is an

excellent solution for cool roofs.
